If your dog’s tongue is hanging out, it might be a health issue: here’s what you should do

We’ve all seen it – a dog lounging with its tongue hanging out, looking completely at ease. While this can be a sign of relaxation, a constantly lolling tongue may indicate an underlying health issue.

Why do dogs stick their tongues out?

Dogs use their tongues to regulate body temperature, particularly after exercise or in warm weather. However, if your dog’s tongue consistently hangs out – even when they’re at rest – it might be more than just a quirky trait.

Possible causes of a constantly hanging tongue

Several factors can cause a dog’s tongue to hang out persistently:

1. Genetics

Some breeds, particularly brachycephalic (flat-faced) dogs like Pugs, Bulldogs, and Shih Tzus, have tongues that are proportionally too large for their mouths. This can lead to their tongue naturally slipping out.

2. Dental issues

Missing teeth—especially the lower canines—can make it difficult for a dog to keep their tongue in place, causing it to hang out more frequently.

3. Neurological problems

Certain neurological conditions or nerve damage from injury or disease can impair tongue control, leading to a persistently protruding tongue.

4. Trauma or injury

Injuries to the jaw, mouth, or facial nerves can cause permanent changes in tongue position. Scarring or muscle damage may also contribute to the issue.

5. Hanging tongue syndrome

Some dogs develop a condition known as Hanging Tongue Syndrome, where the tongue lacks normal muscle function and control. This can be a congenital condition or develop later due to neurological or structural abnormalities.

When should you be concerned?

If your dog’s tongue is consistently hanging out, keep an eye on these warning signs:

• Dryness or cracking: an exposed tongue can dry out, leading to discomfort, cracking, or even bleeding.
• Difficulty eating or drinking: if your dog struggles to eat or drink properly, the issue may be affecting their quality of life.
• Bad breath: a constantly exposed tongue can harbor bacteria, leading to persistent bad breath (halitosis).
• Changes in color or texture: a healthy tongue should be pink and moist. If it appears discolored, swollen, or ulcerated, seek veterinary care immediately.

What to do if your dog’s tongue hangs out constantly

If you notice any concerning symptoms, schedule a visit with your veterinarian. They can diagnose the underlying cause and recommend appropriate treatment, which may include:

• Dental care: addressing missing or damaged teeth that could be contributing to the issue.
• Medication: treating inflammation, pain, or underlying neurological conditions.
• Surgery: in severe cases, corrective procedures may be necessary.

How to manage the condition at home

Even if your dog’s hanging tongue isn’t a medical emergency, you can take steps to keep them comfortable:

✔ Ensure proper hydration – always provide fresh water to prevent dryness.

✔ Monitor tongue health – check regularly for signs of dryness, cracking, or discoloration.

✔ Protect against extreme temperatures – limit exposure to extreme heat or cold, as an exposed tongue is more vulnerable to burns or frostbite.

Final thoughts

While some dogs naturally have tongues that hang out – and we know your best friends better than anyone – it’s important to stay alert for any signs of discomfort or health issues. If your dog’s tongue is constantly exposed and showing signs of dryness, difficulty eating, or other concerning symptoms, consult your veterinarian to ensure they stay happy, healthy, and comfortable.
